In this International Year of Light, it is particularly appropriate to review the historical concept of what is light and the controversies surrounding the extent of the visible spectrum. Today we recognize that light possesses both a wave and particle nature. It is also clear that the limits ...

The color spectrum is the entire range of light wavelengths visible to the human eye.These range from approximately 400 nanometers per wavelength, at the violet end of the spectrum, to 700 nanometers per wavelength, at the red end of the spectrum. Spectral colors refer to those colors that ...
We’re all familiar with sunshine, but did you know there are many different kinds, including infrared, ultraviolet, and many shades of visible sunlight?
A Continuum is a seamless progression of elements, while a Spectrum refers to a range, often of colors or wavelengths.
What is RGB (red, green and blue)? RGB (red, green and blue) refers to a system representing the colors used on a digital display screen. Red, green and blue can be combined in various proportions to obtain any color in the visible spectrum. ...
Blue light, part of the visible light spectrum, is emitted from the sun (the most powerful source of blue light), as well as artificial sources, including digital devices. While, even indoors, the sun is the largest source of blue light, blue light is also found in the LEDs of our dom...
The kind of light humans can see with their eyes is called visible light. The visible light spectrum is made up of various wavelengths, each corresponding to different colors. Other properties of the visible light spectrum include wave-particle duality,

Even with the sun’s light which is thought to be continuous since we see rainbows after it rains. There are often gaps where nothing is visible when the light is analyzed in detail through a spectrometer. A truly continuous spectrum should not have any gaps and identifying gaps in the sun...
